Journal ArticleDOI
Dynamic Clustering in Active Colloidal Suspensions with Chemical Signaling
TL;DR: The experimental results are reproduced mathematically by a chemotactic aggregation mechanism, originally introduced to account for bacterial aggregation and accounting here for diffusiophoretic chemical interaction between colloidal swimmers.
Journal ArticleDOI
Aggregation-fragmentation and individual dynamics of active clusters.
TL;DR: An exhaustive description of the cluster dynamics in apolar active matter is proposed, using large statistics gathered on Janus colloids to measure the aggregation and fragmentation rates and rationalize the resulting cluster size distribution and fluctuations, and establishing a simple, generic model of cluster phase.
Journal ArticleDOI
Nonequilibrium Equation of State in Suspensions of Active Colloids
Félix Ginot,Isaac Theurkauff,Demian Levis,Christophe Ybert,Lydéric Bocquet,Ludovic Berthier,Cécile Cottin-Bizonne +6 more
TL;DR: In this paper, the authors show that activity induces a nonequilibrium adhesion between colloidal microspheres, quantified by an activity-dependent equation of state, which is called active matter.
Journal ArticleDOI
Nonequilibrium equation of state in suspensions of active colloids
Félix Ginot,Isaac Theurkauff,Demian Levis,Christophe Ybert,Lydéric Bocquet,Ludovic Berthier,Cécile Cottin-Bizonne +6 more
TL;DR: In this paper, the authors use sedimentation experiments to probe the nonequilibrium equation of state of a bidimensional assembly of active Janus microspheres, and conduct computer simulations of a model of self-propelled hard disks.
Journal ArticleDOI
Active colloids segmentation and tracking
Xiaofang Wang,Boyang Gao,Simon Masnou,Liming Chen,Isaac Theurkauff,Cécile Cottin-Bizonne,Yuqian Zhao,Frank Y. Shih +7 more
TL;DR: This work addresses the problem of segmenting and tracking colloids in long video sequences corrupted with severe illumination changes by proposing a very accurate method to recover the individual trajectory of each colloid.
